Spanende Bearbeitungsverfahren wie beispielsweise ein Plan-Seiten-Schleifen erzeugt an den Kanten der spanend bearbeiteten Flächen der Werkstücke Grate.Machining processes, such as plan-side grinding, create burrs at the edges of the machined surfaces of the workpieces.

Die Ausbildung der Grate und damit ihre Stärke und Häufigkeit ist unterschiedlich und hängt vom Werkstückwerkstoff und den spanenden Bearbeitungswerkzeugen ab. Die Grate bestehen dabei aus nicht vollständig abgetrenntem Werkstückwerkstoff. Diese Materialteile können während der Montage stören und gar zum Ausfall ganzer Komponenten führen, wenn sie nicht beseitigt worden sind und sich später im Betrieb lösen.The formation of the burrs and thus their strength and frequency varies and depends on the workpiece material and the machining tools. The burrs consist of not completely separated workpiece material. These pieces of material can interfere during assembly and even lead to the failure of entire components, if they have not been eliminated and later dissolve in operation.

Beispielsweise kann - wie in den Figuren 1 und 3 dargestellt - vorgesehen sein, dass die Antriebseinrichtung 5 für die Werkstückaufnahmen 3a-3c ein zentrales Trägerelement 8 aufweist, auf dem drei Antriebsrollen 8a-8c angeordnet sind, die im Wirkeingriff mit den zugeordneten Werkstückaufnahmen 3a-3c bringbar sind und derart die jeweiligen Werkstückaufnahmen 3a-3c drehantreiben.The person skilled in the art knows a number of ways in which he has to design the drive device 5 for the workpiece holders 3a-3c in order to achieve the above-described mode of operation. For example - as in the FIGS. 1 and 3 illustrated - be provided that the drive means 5 for the workpiece holders 3a-3c a central support element. 8 on which three drive rollers 8a-8c are arranged, which are engageable in operative engagement with the associated workpiece holders 3a-3c and thus driving the respective workpiece holders 3a-3c.

Wie am besten aus der Figur 3 ersichtlich ist, sind die Bürstwerkzeuge B1, B2 derart angeordnet, dass der Abstand ihrer Bürstflächen B1' und B2' geringer als die Dicke des zu bearbeitenden Werkstücks W1-W3 ist. Hierdurch wird in vorteilhafter Art und Weise erreicht, dass die Werkstücke W1-W3 durch den von den Bürstwerkzeugen B1, B2 ausgeübten Druck ungespannt in den Werkstückaufnahmen 3a-3c gehalten werden, so dass in vorteilhafter Art und Weise bei der beschriebenen Vorrichtung 1 keine Magnethalterung für die Werkstücke mehr vorhanden sein muß, wie dies bei den bekannten Vorrichtungen der Fall ist.How best of the FIG. 3 is apparent, the brushing tools B1, B2 are arranged such that the distance of their brushing surfaces B1 'and B2' is less than the thickness of the workpiece to be machined W1-W3. This achieves in an advantageous manner that the workpieces W1-W3 are held by the pressure exerted by the brush tools B1, B2 pressure unstressed in the workpiece holders 3a-3c, so that in an advantageous manner in the described device 1 no magnetic holder for the workpieces must be more present, as is the case with the known devices.

Um den Verschleiß der Borsten der Bürstwerkzeuge B1 und B2 kompensieren zu können, ist vorzugsweise vorgesehen, dass die Bürstwerkzeuge B1 und B2 auf Schlitten (nicht gezeigt) montiert sind. Die Schlitten werden über Gewindetriebe kontrolliert zugestellt. Es wird hier bevorzugt, dass die Lage der einzelnen Bürstwerkzeuge B1 und B2 durch taktile Sensoren 20 a, 20b (siehe Figur 4) überwacht wird, die ebenfalls von den Bürsten überstrichen werden.In order to be able to compensate for the wear of the bristles of the brushing tools B1 and B2, it is preferably provided that the brushing tools B1 and B2 are mounted on carriages (not shown). The carriages are controlled by screw drives. It is here preferred that the position of the individual brushing tools B1 and B2 by tactile sensors 20a, 20b (see FIG. 4 ), which are also swept by the brushes.

In Figur 2 ist nun eine zweite Ausführungsform einer Werkstückaufnahme 3' gezeigt, welche sich von den Werkstückaufnahmen 3a-3c der Figur 1 dadurch unterscheiden, dass in die Werkstückaufnahme 3' mehrere Werkstücke W1'-W8' einsetzbar sind und dann gleichzeitig einem Bürstvorgang unterzogen werden können.In FIG. 2 Now, a second embodiment of a workpiece holder 3 'is shown, which extends from the workpiece holders 3a-3c of FIG. 1 differ in that in the workpiece holder 3 'a plurality of workpieces W1'-W8' can be used and then subjected to a brushing process simultaneously.

Bei obigen Ausführungen wird davon ausgegangen, dass die Werkstückaufnahmen 3a-3c durch die Vorrichtung 1 bewegende Transporteinrichtung 2 eine Transportscheibe 3 aufweist, die die in den Werkstückaufnahmen 3a-3c, 3' aufgenommenen Werkstücke W1-W3, W1'-W8' in einer kreisförmigen Bewegung durch die Vorrichtung 1 transportiert. Diese kreisförmige Transportbewegung der Werkstücke W1-W3. W1'-W8' durch die Schleifmaschine 10 ist aber nicht zwingend. Vielmehr ist es auch möglich, anstelle der Transportscheibe 3 und des sie antreibenden Drehantriebs einen Transportschieber mit einem linearen Antrieb vorzusehen, der die Werkstückaufnahmen 3a-3c, 3' mittels einer geradlinigen Verschiebebewegung durch die Vorrichtung 1 transportiert, wobei vorzugsweise vorgesehen ist, dass die Transportbewegung eine periodische Bewegung um die Mittellage eines derartigen Transportschiebers bewirkt.In the above embodiments, it is assumed that the workpiece holders 3a-3c by the device 1 moving transport device 2 comprises a transport disk 3, the in the workpiece holders 3a-3c, 3 'recorded workpieces W1-W3, W1'-W8' in a circular Movement transported by the device 1. This circular transport movement of Workpieces W1-W3. W1'-W8 'through the grinding machine 10 is not mandatory. Rather, it is also possible, instead of the transport disc 3 and the driving rotary drive to provide a transport slide with a linear drive, which transports the workpiece holders 3a-3c, 3 'by means of a linear displacement movement through the device 1, wherein it is preferably provided that the transport movement causes a periodic movement about the central position of such a transport slide.

Vorzugsweise ist vorgesehen, dass die Bewegung der einzelnen Werkstückaufnahmen 3a-3c, 3' und/oder der Transportscheibe 3 oder des Transportschiebers durch eine entsprechende Regelung oder Steuerung der Antriebseinrichtung 5 sowohl in ihrer Größe als auch in ihrer Richtung einstellbar ist, so dass insbesondere die Drehrichtung der Werkstückaufnahmen 3a-3c, 3' während der Bearbeitung umkehrbar ist, so dass hierdurch in vorteilhafter Art und Weise alle Konturkanten der zu bearbeitenden Flächen der Werkstücke W1-W3, W1'-W8', unabhängig von ihrer Orientierung, überstrichen werden.It is preferably provided that the movement of the individual workpiece holders 3a-3c, 3 'and / or the transport disk 3 or the transport slide can be adjusted both by their size and in their direction by appropriate regulation or control of the drive device 5, so that in particular the Direction of rotation of the workpiece holders 3a-3c, 3 'is reversible during processing, so that in an advantageous manner all contour edges of the surfaces to be machined of the workpieces W1-W3, W1'-W8', regardless of their orientation, are swept.

In Figur 4 ist nun eine Ausführungsform der taktilen Sensoren 20a, 20b einer Sensoreinrichtung 20 dargestellt, welche zur Erfassung der Lage der Bürstenflächen B1' und B2' der Bürstwerkzeuge B1 und B2 dient. Jeder der beiden Sensoren 20a, 20b der Sensoreinrichtung 20 weist einen Tastfinger 21 a bzw. 21 b auf, welcher von den Bürstenflächen B1', B2' überstrichen wird. Aus der bei Beaufschlagung der Tastfinger 21a, 21b der Sensoren 20a, 20b der Sensoreinrichtung 20 ist dann in einfacher Art und Weise die Lage der Bürstenflächen B1' und B2' ableitbar, so dass eine Verschleißkompensation der Borsten der Bürstflächen B1', B2' besonders einfach durchführbar ist.In FIG. 4 Now, an embodiment of the tactile sensors 20a, 20b of a sensor device 20 is shown, which serves for detecting the position of the brush surfaces B1 'and B2' of the brush tools B1 and B2. Each of the two sensors 20a, 20b of the sensor device 20 has a sensing finger 21a or 21b, which is swept by the brush surfaces B1 ', B2'. The position of the brush surfaces B1 'and B2' can then be derived in a simple manner from the force applied to the touch fingers 21a, 21b of the sensors 20a, 20b of the sensor device 20 so that wear compensation of the bristles of the brush surfaces B1 ', B2' is particularly simple is feasible.
